[0001] The present application relates to the technical field of refrigeration, and more specifically, relates to an air conditioning unit. Background

[0002] In recent years, with the vigorous development of data centers, the application demand for computer room air conditioners has become increasingly extensive. With the increase in server equipment, air conditioning equipment is required to have larger cooling capacity and larger air volume, while the cooling capacity and air volume of existing traditional computer room air conditioners are relatively small, and multiple units need to operate simultaneously to meet the demand for cooling capacity and air volume.

In the process of implementing the invention, the inventor found that at least the following problem exists in the prior art: under the design conditions of different unit sizes, different electrical layouts and different components, the electrical wiring, cable length and component positions all need to be redesigned and considered, which makes the standardized design of the units difficult and the design modification for new demands also difficult, resulting in a low degree of electrical standardization. Contents of Utility Model

[0004] The embodiments of the present application provide an air conditioning unit, which can meet the unified wiring of electrical design for models with different components and different sizes, and improve the degree of electrical standardization in the unit.

[0005] The air conditioning unit provided by the present application adopts the following technical solutions:

[0006] An air conditioning unit, comprising:

[0007] a rack;

[0008] an electric control module, which is arranged in the middle area of the rack, and the electric control module is arranged close to one side of the rack;

[0009] a component module and a condenser, the component module and the condenser are arranged on the rack around the electric control module as the center, and fans of the component module and the condenser are both electrically connected with the electric control module.

[0010] In some technical solutions, the rack includes an upper layer area and a lower layer area, the condenser is arranged in the upper layer area, the component module and the electric control module are arranged in the lower layer area, and the component module is arranged on one side of the electric control module.

[0011] In some technical solutions, the component module includes a liquid storage tank and a compressor, the liquid storage tank, the compressor and the condenser are arranged in a triangular shape, and the electric control module is arranged at the exact center of the triangle.

[0012] In some technical solutions, the electrical control module includes a high-voltage box and a low-voltage box, which are located on the same side of the rack.

[0013] In some technical solutions, the fan is located at the top of the condenser, and there are multiple sets of condensers and fans that correspond one-to-one; multiple sets of condensers are arranged side by side along the length of the frame, and the power distribution box and the low-voltage distribution box are arranged side by side along the length of the frame.

[0020] With the electronic control module at the center of the air conditioning unit, the component modules and other parts such as the condenser are arranged around the electronic control module. On the one hand, this allows the electronic control module to have its wiring radiating outwards from the center, ensuring that the wiring of components in different modules throughout the unit ultimately leads to the electronic control module, achieving centralization of the wiring. The distance from all components to the electronic control module is also appropriate and close, reducing assembly difficulty. On the other hand, the relative positions, cable lengths, wiring paths, and wiring fixation between each component and the electronic control module can be kept consistent or standardized, achieving a high degree of standardization in electrical cables, electrical paths, and electrical assembly. This allows for complete compatibility of wiring and cabling for different components and unit sizes, ensuring that the wiring and cabling are compatible with different unit lengths. Regardless of changes in the length and width of the unit, the component positions and wiring design remain unchanged. The electronic control module is always placed in the center with wiring radiating outwards, and the process route is fixed. This facilitates the addition, deletion, and modification of components and wiring, reducing the workload of redesign and enabling rapid implementation of new design changes in routing and cable layout.

[0028] This application provides an air conditioning unit that can meet the unified wiring requirements of electrical design for different components and different sizes of units, thereby improving the standardization of electrical systems within the unit.

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, and not all of them. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0030] When modular air conditioning units are designed with different unit sizes, electrical layouts, and components, the electrical wiring, cable lengths, and component locations all need to be redesigned and considered. This makes standardized design of the units difficult, and modifications to meet new requirements are also challenging, resulting in a low degree of electrical standardization. To effectively solve the above technical problems, this application discloses an air conditioning unit.

[0031] Please see Figures 1 to 3 This is one embodiment of an air conditioning unit in this application. The air conditioning unit includes a frame 1, an electrical control module 2, a component module 3, and a condenser 4. A fan 5 is provided on the top area of ​​the condenser 4.

[0032] Specifically, the electrical control module 2 is located in the central area of ​​the frame 1, with the module positioned closer to the frame 1. The component modules 3 and condenser 4 are arranged around the electrical control module 2, and their fans 5 are electrically connected to it. This structural layout, with the electrical control module 2 at the center of the air conditioning unit, and the other components such as the component modules 3 and condenser 4 arranged around it, serves two purposes. First, it allows for a centrally radiating wiring arrangement from the electrical control module 2, ensuring that wiring from different modules within the unit ultimately converges to it, achieving centralization of the wiring and making the distances from all components to the electrical control module 2 more suitable and closer, thus reducing assembly difficulty. Second, the relative positions, cable lengths, wiring paths, and wiring fixation between each component and the electrical control module 2 can be kept consistent or standardized, achieving a high degree of standardization in electrical cabling, electrical paths, and electrical assembly.

[0033] It is worth mentioning that the structural layout with the electronic control module 2 as the center of the air conditioning unit can meet the coding of the whole unit size, and meet the needs of different components and different sizes of models. The wiring and cabling can be fully compatible with different unit lengths. No matter how the length and width of the unit change, the position of the components and the wiring design can be kept unchanged. The electronic control module 2 is placed in the middle and the wiring radiates outward from the center. The process route is fixed, which facilitates the addition, deletion and modification of components and wiring, reduces the workload of redesign, and thus quickly realizes the layout of new design changes and cable layout.

[0034] In traditional designs, components are located on both sides of the electrical control area, with wires running from both sides to the middle, where they converge and stack. In this application, the electrical control module 2 is positioned closer to the rack 1, making full use of the space within the unit for wiring. Components are concentrated along the edge, forming an electrical installation area. Because the electrical control is concentrated on one side, the other side is completely free, allowing refrigerant piping, sensor wires, etc., to run along the empty side without crossing the electrical installation area. This transforms space utilization from "cross-squeezing" to "partitioned parallelism," resulting in clear wiring paths and reducing the risk of wires being squeezed on the same side. During maintenance, only one panel needs to be opened, preventing the wiring on the other side from becoming tangled.

[0035] The rack 1 includes an upper area and a lower area. The condenser 4 is located in the upper area, and the component module 3 and the electronic control module 2 are located in the lower area, with the component module 3 located on one side of the electronic control module 2. There are multiple sets of condensers 4 and fans 5, which correspond one-to-one, and the multiple sets of condensers 4 are arranged side by side along the length of the rack 1. Condenser 4, as the hottest component of the system, is fixedly installed in the upper area. It can directly utilize the principle of hot air rising and vertically exhaust heat through the top fan 5, preventing heat from diffusing downwards to the lower area. After the condenser 4 is moved upwards, the lower area is no longer exposed to high-temperature radiation, the ambient temperature decreases, and the device module 3 and the electrical control module 2, located in the lower area, can maintain normal operation, extending the service life of each component. Secondly, after the "lower cooling and upper heating" stratification, the wiring between device module 3 and electrical control module 2 is concentrated on the same side of the rack 1, and the wiring is physically isolated from the refrigerant pipes, eliminating the risk of "pipe pressing on wires" and reducing EMC interference. At the same time, during maintenance, device module 3 and electrical control module 2 can be operated simply by opening the lower area side panel of rack 1, without having to cross the high-temperature condenser 4, avoiding the risk of burns from the top and tools falling.

[0036] Module 3 includes a liquid receiver, a compressor, and a refrigerant pump. All three are fixedly mounted on frame 1, with the compressor located at one end of the refrigerant pump. The refrigerant pump and the liquid receiver are connected via piping. The liquid receiver, compressor, and condenser 4 are arranged in a triangular configuration, with the electrical control module 2 positioned in the center. It is understandable that the liquid receiver, compressor, and condenser 4 are large in size and mass; arranging them in a triangular configuration creates an isosceles triangle, with the overall center of gravity resting at the center of the triangle. Since the compressor vibrates the most, it is placed at one corner of the triangle, and the condenser 4, which has a similar mass, is located at its opposite corner. The line connecting the centers of mass of the two passes through the center of gravity of the whole machine. The liquid receiver is located at the third corner as a "counterweight", forming a natural dynamic balance. The electronic control module 2 is located at the vibration node (the point of minimum amplitude). Secondly, the wiring paths of the liquid receiver, compressor and condenser 4 are shorter, the wiring space is more planar and larger, the wiring distance of key components is greatly reduced, saving costs and making wiring more convenient.

[0037] The electrical control module 2 includes a high-voltage box 21 and a low-voltage box 22, which are located on the same side of the frame 1. Furthermore, the high-voltage box 21 and low-voltage box 22 are arranged side-by-side along the length of the frame 1, and are adjacent to each other. This reduces wiring length, facilitates maintenance, and improves operational convenience. The centrally located adjacent layout of the high-voltage box 21 and low-voltage box 22 ensures that their outlets are always aligned with the same coordinate reference for each component. Even if the overall size of the unit is increased, only the frame 1 is widened, while the total thickness and position of the high-voltage box 21 and low-voltage box 22 remain unchanged. The cable routing is only shifted along the length direction. The component layout, wiring harness numbering, PLC program, and test fixtures within the high-voltage box 21 and low-voltage box 22 can all be reused. Meanwhile, with the widening of the casing, the distance between the high-voltage box 21 and the low-voltage box 22 and the compressor is increased proportionally. However, the length of the adjacent, shared ground plane between the high-voltage box 21 and the low-voltage box 22 is also increased, which reduces the ground impedance.

[0038] It is important to emphasize that the electrical control box 21 maintains complete consistency in electrical layout, installation dimensions, and interface definitions, ensuring compatibility with different unit sizes. Although refrigerant pump air conditioning units of different cooling capacities (3 / 4 / 5 HP) differ in physical dimensions and component power ratings, the installation positions, guide rail dimensions, terminal block layouts, and control board interfaces of these components are standardized. Their electrical control boxes 21 (i.e., the main electrical control box) can be interchanged or share a design platform, thereby enabling different cooling capacity units to use the same electrical installation drawing, the same set of sheet metal molds, and the same assembly line, significantly reducing design and manufacturing costs while balancing large-scale production and flexible configuration.

[0039] Device module 3 also includes a reactor box mounted on rack 1, with a high-voltage box 21 positioned between the reactor box and the low-voltage box 22. The output terminals of the reactor box are mirror-aligned with the input terminals of the high-voltage box 21, and the output terminal blocks of the high-voltage box 21 are mirror-aligned with the sensor terminal blocks of the low-voltage box 22. Wiring is bundled before insertion to avoid the risk of cold solder joints caused by "installing before soldering." The reactor, high-voltage, and low-voltage components are arranged in a straight line, effectively compressing the high-current filtering, power switching, and signal control into a single line, achieving the shortest copper busbar and the smallest loop. This layout allows for the addition or removal of components in the computer room air conditioning system at different cooling capacities while maintaining a zero-redesign effect.

[0040] Inspection doors 23 are provided on the same side wall of the high-voltage box 21 and the low-voltage box 22 for convenient maintenance or replacement. The inspection doors face the front of the frame 1. When it is necessary to replace the main board or contactor, only the inspection door needs to be opened. The operation depth is small, there is no need to crawl into the unit, and the average maintenance time is shortened.

[0041] Please see Figure 1This air conditioning unit is designed to operate independently as a refrigerant pump refrigeration system. This independent refrigerant pump refrigeration system unit consists of three V-type condensers, an evaporator, a compressor system, and a refrigerant pump system. This air conditioning unit fully utilizes outdoor natural cooling sources, reducing unit energy consumption. It achieves three circulation systems within the same refrigeration system: "compressor mode, compressor and refrigerant pump mixed mode, and refrigerant pump independent operation mode." Its highly integrated design results in a high energy efficiency ratio and significant energy-saving effects. In this air conditioning unit, the liquid storage tank, compressor, refrigerant pump, and other electrical control modules 2 used in the piping are connected to the strong and weak current boxes respectively via cables according to the principle of electrical control and the separation of strong and weak current. The strong and weak current boxes are fixed on one side of the middle area along the length of the frame 1, and the strong current box 21 and the weak current box 22 are arranged side by side and adjacent to each other. The wiring radiates outward from the strong and weak current boxes 22 as the center, and the other components are arranged around the center, so that the relative position of each component and the electrical control center, the cable length, the wiring path, and the wiring fixation can be kept consistent or uniformly standardized, thereby improving the standardization of electrical systems in the unit.

[0042] Please refer to Figure 2 and Figure 3 , Figure 2 The air conditioning unit in the middle includes four V-type condensers 4, Figure 3 The air conditioning unit includes five V-shaped condensers 4. Although the corresponding cooling capacity levels of the air conditioning units are different, and their sizes vary (external sheet metal, heat exchanger size, number of fans 5, etc. vary with cooling capacity), and the selection of components is different (such as different compressor power, different refrigerant pump power, different electric heating power), the installation positions, guide rail dimensions, wiring terminal layouts, and control board interfaces of these components are all unified. When facing three different body widths of 3 / 4 / 5V (three horsepower, four horsepower, and five horsepower), each component is added at both ends along the length of the frame 1. The positions of the strong and weak current boxes 22 are always arranged adjacent to each other on the same side of the frame 1, which can meet the centralization of the wiring of the whole unit. The distance from all components to the electrical control is relatively appropriate and close. The wiring and cabling can achieve complete compatibility with different unit lengths, which facilitates the addition, deletion, and modification of components and reduces the workload of redesign.
